Fig. 2: Distribution of GHGSat-observed waste disposal sites and their urban areas.
From: Global satellite survey reveals uncertainty in landfill methane emissions
Location of the 151 waste disposal sites observed by GHGSat satellites, and the 46 out of 130 corresponding urban areas for which methane emission plumes have been detected in TROPOMI data (grey). GHGSat methane emission rate distributions over logarithmically spaced bins are given for all sites (black line), and separately for managed landfills (orange) and dumping sites (purple). This site classification has been manually determined using satellite and aerial imagery from Google Earth (see main text). The red line shows cumulative emissions. The site-level and urban-area-level data supporting this figure are provided in the Supplementary Information.
